GAS BURNER Filed De. 26, 1928 2 Sheets-Sheet 2 11,2702 @any VQIITNESS:ATTORNEY Patented Apr. 1, 1930 UNITED STATES PATENT ens BURNER i,

Application filed December 26, 1928. VSerial No. 328,561.

This invention relates to a gas burner, the general object of theinvention being to provide means whereby the gas is introduced into thebarrel part of the burner between two streams of air so that the gas isthoroughly mixed with the air and there is no danger of backfiring orimproper combustion and damage through burning of the parts of theburner.

Another object of the invention is to provide valves for controlling theentrance of air to the. burner, with means for adjusting the valvessimultaneously.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a top plan view of the burner.

Figure 2 is an enlarged side view of the front end thereof. c

Figure 3 is a top plan View of the front end im thereof, showing thevalves open.

Figure 4 is a longitudinal sectional view, with the valves closed.

Figure 5 is a section on line 5-5 of Figure 4.

Figure 6 is a section on line 6 6 of Figure 4.

In these drawings, the numeral 1 indicates the drum into which gas isintroduced from any suitable source by the pipe 2, this drum having areduced inner end 3 and a tubular member 4 has its flaring mouth formedwith or connected to the annular closure part 5 of said end. Thistubular member is formed with or connected to the other end of the drumand forms a passage through the drum. An annular row of holes 6 isformed in the part 5 for the escape of gas. The barrel or mixing chamberof t-he burner is shown at 7, and this barrel is of the same dimensionsas the reduced part 3 of the drum. The baroFF1cE- rel is spaced from thedrum and the two parts i are connectedtogether at opposite sides by thebrackets 8 which are each formed with offset parts. The air spacevformed between the drum and the barrel is adapted to be closed by a'pair of doors or valves 9, each of which is hinged to the barrel, withtheir free ends overlapping the reduced part 3 of the drum. The sideedges of the doors Valso overlap, as shown at 10, so that when the doorsare closed, no air can enter between thel drum and barrel. The outer endof the passage formed by the tubular member 4 is closed by a cap orvvalve 11 which is formed with the spaced lingers 12 so that when the capis partly pulled from the passage, the spaces between the lingers willpermit air to enter the passage. ,i

A yoke 14 has its bight connected with the outer end of the cap 11 andits limbs passv through openings formed in the brackets 8 and theextremities of its limbs arepivoted totheinner endsof the two pairs oflinks 15 which have their outerends pivoted to the doors, so that whenthe yoke is pulled outwardly, the links willswing the doors to openposition and the bight of the yoke will move the cap 11 to openpositionso that air can enter through the tubular member 4 and throughthe openings left by the doors, thus providingtwo streams of air betweenwhich the gas'is yprojected through they perforations 6. This air andgas will pass through the barrel 7 i By arranging'the air supply asshown, the gas and air are thoroughly mixed `together and there is nodanger of the gas being forced into certain parts of the burner, asthere is if but one stream of air is used. This invention will insureperfect combustion without danger of damage to the barrel throughburning.

As shown, the barrel and drum are of octagon shape and this shape ofbarrel reduces the speed of the gas therethrough and it also prevents awhirling movement of the gas.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claims.

What I claim is 1. A gas burner comprising a drum having perforations inits outlet end and a tubular part passing through the drum and formingan air passage at the center thereof, means for introducing gas into thedrum, a barrel connected with the drum but. spaced therefrom, a pair ofdoors hinged to the drum and movable adjacent the barrel for controlling the passage of air into the space between the drum and barrel, avalve for controlling thevflow of air through the tubular member andmeans for operating the doors and valve simultaneously.

2. A gas'burner comprising a drum having perforations in its outlet endand a tubular part passing through .the drum and forming an air passageat the center thereof, means for introducing gas into the drum, a barrelconnected with the drum but spaced therefrom, valves for controlling thepassage of air into the space between the drum and barrel, a valve forcontrolling the flow of air through the tubular member, means foroperating the-valves simultaneously, said barrel and drum being ofOctagon shape in cross sec-- tion.

3. A gas burner comprising a drum having a centrally arranged tubularpart passing longitudinally therethrough to form an air passage, theinner end of the drum being perforated, means for introducing gas intothe drum,a barrel, means for connecting the barrel to the drum with aspace between they ade jacent ends of the barrel and drum, doors hingedtothe barrel for closing the space, a

cap for closing the outer end of the tubular member and. having inwardlyextending n.

gers thereon spaced apart whereby air will be admitted to the tubularmember when the cap-is partly withdrawn, ayoke-shaped inember having itsbight connected with the cap and its limbs extendingl over the doors andlinks connecting` the ends of the limbs with the doors whereby the doorsand cap willbe moved to open position when the yoke-shaped member ispulled outwardly.

In testimony whereof I affix my signature.

FLOYD WYATT.
